🌐 Mbps 与 Gbps 换算Mbps to Gbps Converter
在 Mbps（兆比特每秒）和 Gbps（吉比特每秒）之间换算（1 Gbps = 1,000 Mbps），同时给出 Kbps、MB/s、GB/s，并可估算按该速率传输一个文件需要多久。Convert between Mbps (megabits per second) and Gbps (gigabits per second) — 1 Gbps = 1,000 Mbps — with Kbps, MB/s and GB/s, and an estimate of how long a file takes at that speed.

「Mbps 与 Gbps 换算」是什么？What is the Mbps to Gbps Converter tool?

如何使用「Mbps 与 Gbps 换算」？How do I use the Mbps to Gbps Converter tool?
在「Mbps 与 Gbps 换算」中，填写「方向」、「速率（Mbps）」、「速率（Gbps）」、「文件大小（GB，可选）」等参数，结果会随输入实时计算并显示在下方。In the Mbps to Gbps Converter: Fill in "Direction", "Speed (Mbps)", "Speed (Gbps)", "File size (GB, optional)"; results are recalculated instantly as you type.
1 Gbps 等于多少 Mbps？How many Mbps are in 1 Gbps?
1 Gbps = 1,000 Mbps。网络速率使用十进制（SI）前缀：1 Gbps = 10⁹ 比特每秒，1 Mbps = 10⁶ 比特每秒，不是 1,024 倍。1 Gbps = 1,000 Mbps. Network speeds use decimal (SI) prefixes — 1 Gbps = 10⁹ bits per second and 1 Mbps = 10⁶ — not factors of 1,024.
Mbps 和 MB/s 有什么区别？What's the difference between Mbps and MB/s?
小写 b 是比特（bit），大写 B 是字节（byte），1 字节 = 8 比特。所以 1,000 Mbps 的宽带理论下载速度是 125 MB/s。下载软件显示的往往是 MB/s。Lower-case b is bits and upper-case B is bytes, with 1 byte = 8 bits. A 1,000 Mbps connection therefore downloads at up to 125 MB/s in theory; download managers usually show MB/s.
传输时间准吗？Is the transfer time accurate?
它是理论最短时间：文件大小（GB，按 10⁹ 字节）× 8,000 ÷ 速率（Mbps）秒。实际还有 TCP/IP 协议开销、网络拥塞和硬盘速度限制，通常会慢 5%–10% 或更多。It's the theoretical minimum: file size (GB, as 10⁹ bytes) × 8,000 ÷ speed in Mbps seconds. Real transfers lose time to TCP/IP overhead, congestion and disk speed, typically 5–10% or more.
换算系数准确吗？Are the conversion factors exact?
「Mbps 与 Gbps 换算」采用国际单位制（SI）或公认标准中的定义值作为换算系数，结果保留约 10 位有效数字。The Mbps to Gbps Converter uses factors defined by the SI or other recognised standards and shows about 10 significant digits.
「Mbps 与 Gbps 换算」免费吗？需要注册吗？Is the Mbps to Gbps Converter free? Do I need an account?
